ROLLER WINDOW-SCREEN.

Specification of Letters Patent.

Application filed October 24, 1910.

Patented Sept. 12, 1911.

Serial No. 588,873.

To all whom it may concern:

Be it known that I, JASPER BLACKBURN, a citizen of the United States, and resident of Kirkwood, St. Louis county, Missouri, have invented certain new and useful Improvements in Roller Window-Screens, of which the following is a specification containing a full, clear, and exact description, reference being hadto the accompanying drawings, forming a part hereof.

My invention relates to improvements in roller window screens, the object of my invention being to construct a simple, neat and inexpensive roller screen attachment for windows, in which there is a housing carried by the lower rail of the sash having therein a spring roller upon which the screen may be rolled in such manner as to conceal the roller and to provide an end strip for the screen which may be locked to the sill and which end strip serves to completely inclose the roller and screen, thereby holding the screen in a weather-tight compartment.

A further object of my invention is to construct an improved means for holding the screen against the parting strip.

With the above purposes in View my invention consists in certain novel features of construction and arrangement of parts as will be hereinafter more fully described, pointed out in the claims and illustrated by the accompanying drawings, in which- Figure 1 is an inside face view of a window equipped with my improved invention; Fig. 2 is an enlarged, vertical, sectional view taken on the line 22 of Fig. 1; Fig. 3 is an inside face view partly in section and illustrates the window in a closed position; Fig. 4 is an enlarged, sectional plan taken on the line 44 of Fig. 1; Fig. 5 is an enlarged, vertical, sectional elevation illustrating the lower sash partially raised and the roller screen wholly inclosed in the housing carried by the lower sash; Fig. 6 is an enlarged face view illustrating the lower portion of the end of the sash together with the means for holding the screen against the parting strip, which means in this figure are shown heldsaway from the screen by the .50 sash; Fig. 7 is a vertical, sectional elevation illustrating the window in a closed position and the strip carried by the screen secured to the sill; and Fig. 8 is a sectional plan taken on the line 8-8 of Fig. 7

Referring by numerals to the accompanying drawings: 1 designates the sill, 2 the jambs and 3 the stops of the window, all of which may be of ordinary construction.

4 designates the lower rail of the lower sash which is substantially the same as the sash now in common use except for its vertical dimension which is considerably less than the present rail. Secured to the outer face of the rail is a sheet metal wall 5 extending from end to end of the rail and the wall, as shown in Fig. 2, is preferably countersunk in the outer face of the rail. The inner face of the rail is countersunk in the same manner as the outer face and secured therein is a sheet metal member 6 con stituting the rear wall and carried thereby, preferably formed integrally therewith, is the bottom 7, the free end of which extends to a point adjacent the wall 5, thereby forming a longitudinal slot extending the full length of the rail. The walls 5 and 6 and the bottom 7 form a housing for the inclosure of a roller, such as 8 which is of the common type known as spring rollers. Secured in any desired manner to the roller is the upper margin of a screen 9 which is 7 arranged to roll upon the roller 8 and is of a suflicient width to extend from jamb to jamb of the window.

10 and 11 designate end plates secured to the end faces of the lower rail in which the journals 12 and 18 of the roller are mounted, the plate 10 having a circular journal hearing and the plate 11 having an angular bearing in which is mounted the angular journal of the roller.

Secured to the end of the screen 9, opposed to its end secured to the roller, is a strip 14 having an up-turned outer end 15 .to which the lower margin of the screen is attached and within the strip 14 there are slots 16 through which the screw-eyes 17 project when the strip is brought to the sill. Carried by the strip 14 is a bolt 18 which is secured to the strip by a rivet 19 or the like, there being a slot 20 in the body of the bolt to permit its movement relative the rivet. The bolt is preferably formed fro-m sheet metal and its outer end is reduced to such size to permit its entering the eye 17, the end of the bolt, opposite its reduced end, peing turned upwardly to afford a hand 101d.

21 designates openings formed in the bottom piece 7 of the housing which are arranged in such positions vertically alining with the draw bolts so as to permit them to project through the bottom 7 as shown in Fig. 5.

In order that the strip 1& will not hold sponding with the thickness of the strip 14.

23 designates the parting strips which, as. shown, are of some considerable tlllCkIlGSS so as to project laterally from the jamb a greater distance than the stop 3 so as to make a face against which the side margins of the screen may be held, as shown in Fig. 4:.

24 designates an arnrpivotally mounted upon the screw 25, which arm is actuated in one direction by a coil spring26 embracing the screw 25, having its one end secured to the screw and its other end secured to the arm 24. Carried by the outer free end of the arm is a shoe 27 which is preferably formed from leather or the like and arranged to engage with the screen and securely hold it in place against the parting strip 23.

28 designates rollers, carried by the arm 24: intermediate its ends, which are ar ranged for engagement with the side rails of the sash so as to move the shoe away from the screen.

In the operation of the device, assuming that the walls 5 and 6, the bottom 7 and the end plates 10 and 11 are secured to the lower rail of the sash, as shown, it is apparent that they form a housing in which to hold and carry the roller 8 and the screen 9 when not in use and, by reason of the 01f i I set 22 in the bottom 7, it is obvious that the bottom 7 may be drawn to the upper face of the sill over the strip 14. If it be desired to use the screen, the strip 14 may be locked to the sill by means of the bolts 18 and screw-eyes 17 hence, when the window is raised, the opening will be tightly screened. the bottom 7 away from the sill, I have. formed in the bottom the ofi-set 22 which, as shown in Fig. 7, is of a height col-re I am aware that roller screens have been applied to windows, in some instances the roller has been carried by the sash and the screen fixed to the sill and in other instances the rol'ler was secured to the sill and the screen fixed to the sash, hence I do not means for detachably securing said strip to the window frame.

2. In combination with a spring actuated roller screen carried by the sash of a window and means for securing the free end of the screen to the window frame, of a spring actuated member for holding the screen against the parting strip of the window which member is thrown automatically out of the path of travel of the sash in the manner set forth and for the purposes stated.

In testimony whereof, I have signed my name to this specification, in presence of two subscribing witnesses.
